This invention relates to slicing machines for meat or other material inwhich the sliced material is received automatically and stacked till itis taken away from the machine.

The existing slicing machines of similar type comprising a horizontal orinclined knife and a moving platform provided thereunder in order toreceive the formed slices, have a Very important drawback. The`construction of the inflexible platform which has to receive the slicesnecessitates that there must be a considerable distance between thisplatform and the knife, so that the slice -is` not supported as soon asit is formed, but the front end is hanging down and as the slice isreceived in this position, it will be situated on the platform in foldedmanner after it is cut off and no regular pile of slices is obtained andit is the object of the present invention to avoid this drawback.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur,

Figure 1 is a vertical longitudinal sectional view,

Figure 2 is a fragmentary transverse vertical sectional view,

Figure 3 is a perspective view of the machine,

Figure Yl is an enlarged fragmentary elevational detail of the lockingmeans between the grate and movable frame taken on lines 4-4 of Fig. 2i,

Fig. 5 is a top plan View of the machine partly in section,

Fig. 6 is a front elevation of the machine partly in section,

Fig. 7 is a detail sectional view of bit lifting mechanism, and

Fig. 8 is a detail sectional View of the slide clamping mechanism.

A flexible platform (grate) IA is arranged beneath the horizontal knifeI9, to receive the slices, which are formed.

This platform IA moves in unison with the upper table ID of the machineand comprises a sheet of suitable material or a number of rods I (seeFigures 1 and 2), which are flexibly connected one to another by linksandv which slide in grooves 2B in bars 2 on both sides of the machineframe IB.

These guide bars 2 are supported by the upper branches of bell cranklevers 3, which are fulcrumed about the pins 4 fixed to the frame IB.The guide bars therefore can move together around the pins 4 to acertain extent. The lower branches of the bell crank lever are connectedby a link 3' in order to obtain a regular descend ing movement of theguide bars 2.

The iiy-wheel ZI is mounted on the outer end cf the shaft 23. Shaft 23engages with a gear All carried by shaft 25. Shaft 25 has a gear 26mounted on its upper end, which gear meshes with a pinion 21, which ismounted on the lower end of the blade shaft 28. Shaft 25 is provided atits lower end with a crank I1. Crank l1 is connected by a rod I8 to thebottom portion of the upper table I0.

One of the rods I of the platform (grate) lA extends out of the sidebars 2 in a notch 20 of the i frame 5 (see Figure 4), in which notch ZUthe rod i is locked by the bit 29 on the vertical slidable frame 6. Aroller 'l on the rod I is used to reduce the friction between this rod land the side bars 2 when the side bars 2 and, also, the grate IA in duecourse are directed downwardly by the frame 5, which receives itsvertical motion on the upper table I9 by a half-nut on the feed screwspindle 8. The downward motion of the grate is thus in accordance withthe thickness of the slice.

The working of the mechanism is as follows: The meat or other materialwhich is to besliced is fastened in suitable manner on the slide 9(Figure l). This slide is directed downward by a half-nut (not shown) inmesh with the threaded spindle 8.

The upper table I0, which carries the slide 9, is directed toward andfrom the knife in the usual manner by a crank I1 and a connectingrod I8.

Turning the fly-wheel 2| will rotate the shaft 23.. The shaft 23 engagesshaft 25 and the gear 26 on the shaft 25 will mesh with pinion 21, andthe rotary blade I9 will be rotated. At the same time, when shaft 25 isrotating, it will turn crank Il, which will reciprocate the upper tableto and from the rotary knife I9. The grate IA and slide 9, beingconnected to the upper table IIJ by the bit end of the frame E, fastenedto the end of one of the rods I of the grate IA, will reciprocate withthe upper table IIJ.

As one of the rods I is locked in a notch 20 of the frame 5, which ismounted on the upper table I 0 and only the platform (grate) IA formedby the rods I moves vertically slidable in unison with the upper tableto and from the knife, and

as the frame 5 is directed downward by a halfnut in mesh with thethreaded spindle 8, which spindle is also used for the motion of theslide 9, the frame 5 and the platform IA move downwards in unison withthe slide 9. Frame 5 is connected to slide 9, carrying the material tobe sliced toward the rotary knife I9.

Furthermore, if the bit 20 of the slidable frame 6 is lifted by theleverv I I, the engaged bar I is released from the notch 20 in the frameand the whole grate I can be pulled by hand to the front of the machine.The rods I slide in the grooves 2B in the side bars 2. When positionedat the front of the machine the grate IA, together with the bars 2, arepressed down by hand in such manner that the rods I are directed exactlybetween the backs I2 of the temporary supporting plate I3. In order toensure that the rods I come exactly between the backs of the plate I3, anotch I4 is made in the fixed side plate I5 and the foremost of the rodsI is pressed down into this notch. This engagement is not hampered bythe upper branches of the bell crank levers 3 as they swing about thepins 4 to a positionA shown in dotted lines in Fig. 1.

After the sliced material has been removed v from the platform IA, therods I and side bars 2 are lifted, and, in order to obtain the formerposition of the bars, a stop I6 (Figure 2) is fixed on the frame 5,which stop limits the upward motion of the bars 2. The rods I are nowpushed back till the extending rod I stops in the notch 20 of the frame5 and is locked by the bit 2B of the frame 6. Now the mechanism is readyagain for use.

The slices are accumulated on the grate formed by the bars I, which.grate moves to and from the knife together with the upper table withthe piece of meat to be sliced. Immediately as a slice is being cut itsforward edge and then the complete slice falls flat on the bars I andthe following slice falls just over the last one. The guides 2 descendas the pile of slices increases.

Having thus fully described this invention, I

hereby reserve the benefit of all changes in form, arrangement, order oruse of parts, as it is evident that many minor changes may be madetherein without departing from the spirit of this invention or the scopeof the following claims.

I claim:

1. A slicing machine for meat or other material, comprising a frame, asubstantially horizontally disposed and rotatable disc-knife thereon, aWork holder movable in a substantially horizontal plane toward and awayfrom the knife, a flexible platform arranged under the knife and theWork holder for receiving and stacking the formed slices, curved andgrooved guides mounted for vertical and rocking movement in the framefor rnovably4 supporting the platform close under the edge of the knifeso as to support the slices immediately from the moment of starting thecutting of each slice and allowing descending of the platform with thework as the slicing proceeds, and coupling means between a part of theplatform and the work holder for giving the platform a to-and-fromovement in the guides when the machine is operated.

2. A slicing machine as claimed in claim 1, wherein the coupling meansis of a disengageable type in order that the platform may be movedforwardly in the frame independently of the operation of the workholder.

3. A slicing machine as claimed in claim 1, wherein the coupling meansis of a disengageable type so that the platform may be disconnected fromthe work holder and moved independently thereof, said platform includinga series of flexibly connected rods, means situated at the front of themachine for releasably engaging the foremost rod in order to releasablyhold the platform at the front of the machine.
